I or CEBU, PHILIPrmn 'ISLANLDJS.= o 7 COBRA nix-Ina Application filed July 23, 1929. Serial no. 380,380.

This invention relates to a drier for copra and the like, the general object of the invention being to provide simple means whereby the copra can be dried as well as fumigated through means of a casing properly heated and containing a rotary drum in which the copra is placed, With manually operated means for turning the drum occasionally whereby the heat will come in contact with all portions of the copra. I

Another object of the invention is to provide means whereby the heat will reach the away. I c

material adjacent the center of the drum and also to providemeans for regulating the term perature of the air within the casing.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim. V p 7 In describingthe invention in detail reference will be-had. to the accompanying drawings wherein like characters denote likeior corresponding parts throughout the several views, and in which:-

Figure 1 is an elevation-with partsbroken Inthese views, the letter A indicates a casing preferably of rectangular shape and pro vided with the wheels 1 so that it can be easily transported from place "to place. i The casing is preferably placed over a heating chamber 2 which has a firebox or furnace at one end thereof and a chimney connected with its other end. i Air is supplied to the lower part of the casing through the openings 3 which are controlled by a damper slide 4. A row of these openings is arranged at each side of the casingjandieach row is controlled by a damper plate at each side of the casing; l V

Outlets 5 are arranged in the top of the casing, which are controlled bysuitable valves 6 'shapeofpocketsland aredesigned to permit 7,

shown in full and dotted lines in Figure 2. As before stated, the

so'that-the escape of theair fromthecasing can be regulated;

An upwardly opening door 7 is arranged in each side of the top of the casing for per mitting material to be placed in the drum '8 which has its trunnions 9 suitably journaled I in'the casing. One trunnion is slidably supported in its bearing as shown at 10, so that this end of the drum can beraised through means ofalever 11 pivoted to the, post 12 on theftopof the casing at one end thereof and ,detachably? connected to-the, drum by a link 13 engaging a hook -14: at one end of the drum. A cable 15 is .1. connected with the outer end of the lever for facilitatingthe 1 5 manipulation thereof. A, crank handle 16 is connected with. the-other trunnionso as to impart movement 'tofithehdrum, and latch means 17 are arranged for holding the crank handlein adjusted position. 5 The drum :is 2 composed of a frame covered Witlrwire meshy as-shown at 18', and inwardly extending projections 19,-are arrangedzatiopposite sides ofthe drum, these projections being in the the heated air tote nter the pocket-sand thus reach the interior portions of the drum and act on the material adjacent the central part I i of the drum, The drurnai's provided with an inlet door 20, in one sidthereof and withan outlet door'211inonel'end thereof. o

, .From theforegoing itwillbe seen thatby moving the drumlthrough means ofthe crank handle 16' to a positionwhere the door 20 will be under either one ofthe doors '7 and by openingthe doors 20 and 7, thei'copra can be placed in the drum. "The doors are then closed and the; drum moved to, a position where'one set of pockets willbe at the bottomand the other setiat' the'top. The heated air passing through thdcasingwill come incon tact with the copra and thoroughly heat the same-sothat the copra'zis, quickly dried,..1the

moist air escapingfthrough the outlets 5. The V n5 drum is given a half turn occasionally to facilitate the drying action and this is done by turning the handle '16 from one horizonal po sit-ion to another horizontal position, as p pockets 197 permit the heated air to contact the copra adjacent the center of the drum. When the copra is dried, the crank handle is turned to a vertical position, as shown in dotted lines in Figure 2, which will place the outlet door 21 at the bottom of the drum and then the lever 11 is raised to its dotted line position in Figure 1, after the link is placed in engagement with the hook 14 so that the drum will ,be tilted to the dotted line position shown in Figure 1 and the copra will gravitate through the outlet door into a suitable receptacle. When the copra is to be fumigated by the use of sulphur or the like, the fumigating material is placed in the lower part of the casing through the door 22 in one end of the casing so that the fumes will pass through the material in the drum. 7

Thus I have provided an inexpensive drier for copra and the like which is portable and which will quickly dry or fumigate the copra.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes maybe made in the construction and inthecombination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is I A copra drier comprising upper and lower communicating sections and said lower section adapted-to be positioned over a heating source and having a plurality of air. inlet I opeenings' in the sides thereof and adjacent t lower edges, control slides carried by the sides of said lower section to regulate the flow of air through the o ings, a cover for said upper section and aving elongated doorways, hinged doors on the cover for closing said door-ways, combined heat and air discharge means carried by the cover between said doors, a perforated drum rotatably and slidably mounted in said upper section and having door-ways either of which may be aligned with the first mentioned door-ways I to receive material when the doors are open, closure means for the second mentioned doorways, means for rotating the drum, an elevating device carried by said cover and adapted to be connected to one end of the v drum to incline the latter to discharge the contents thereof from one end, and means at one side of the upper section to permit the contents of the drum to ass outwardly of the upper section when t e drum is inclined. I k V v testimony whereofIaffix my signature.
